According to the ever-helpful wikipedia, he made bedposts from human heads, lampshades and upholster chair seats from skin, soup bowls from skullcaps, a face mask made out of real facial skin found in a paper bag, a necklace of human lips, a waistcoat from a vagina and breasts and other things, including a belt made of nipples and his most infamous, an entire wardrobe fabricated of human skin consisting of leggings, a gutted torso (including breasts) and an array of tanned, dead-skin masks that looked leathery and almost mummified.
